FLASK FOR MOLDING.

)PECIFIGATION forming part of Letters Patent No. 435,040, dated August26, 1890.

Application filed November 4, 1889. $erial No. 329,114. (No model.)

To all whom it may concern.-

Be it known that I, JOHN I. KINSEY, of Easton, in the county ofNorthampton and State of Pennsylvania, have invented certain new anduseful Improvements in Flasks for Molding, of which the following is aspecification, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

The objectand nature of my invention will be fully described and setforth in the following specification and claims.

In the drawings, Figure 1 is a plan of one section of a flask, showingthe pattern in position. Fig. 2 is a similar view showing the patternremoved. Fig. 3 is a transverse section on the line as as, Fig. 1. Fig.4 is a vertical longitudinal section of a portion of Fig. 1.

Similar letters of reference indicate similar parts in the respectivefigures.

A represents one section of the flask, it being of course understoodthat the other section would be a duplicate of the one illustrated anddescribed.

B B are guides supported on a bar or partition 1), extending across eachsection of the flask. The guides B are provided with openings b for thereception of the guards or supports 0 C. One side of each section of theflask is also provided with openings at to admit the insertion of theguards or supports C C, and close to the openings are pivoted thecatches or clamps or, adapted to swing over the openings (1 and supportthe guards C O in the openings at and b.

At one end of each section of the flask a guide D is removably securedby means of the lugs (1. Each guide is perforated at d for the passageof a pin E, and is so arranged that the pin will occupy an equal spacemidway of the top edge of the end wall of each section, said walls beingprovided with a semicircular recess (t to receive it. When the twosections are brought together, the pin will pass through the centralpoint of the end wall of the flask.

F represents the pattern.

Other portions of the apparatus will be referred to in the followingdescription of the operation. To form the mold for a bent pipe, Iproceed in the ordinary way, and in order to insure the centralizing ofthe pattern in the flask a holefis made centrally in the U -shaped endof the pattern, into which the pin E enters after passing through theguide D and the end of the flask. At the same time two guards O areinserted through the openings in the side of the flask and the guides B,and are supported in proper position by the pivoted catches a. TheU-shaped end of the pattern is supported on the guards O and the otherend by means of a staple f, which connects the extensions F of thepipepattern proper.

lVhile I have illustrated and described my invention as applied to moldsfor bent or U -shaped pipes, it is evident that it is equally adaptedfor use in forming molds for a great variety of castings.

Having thus described my invention, I claim- 1. The combination, with aflask and a pattern provided witha hole centrally in one end, of guardsor supports passing through opposite sides of the flask to support thepattern, and a pin passing centrally through one end of the flask andengaging the hole in the pattern, substantially as and for the purposespecified.

2. The combination, with a flask having a bar or partition extendingacross each section and perforated guides secured to said partitions, ofguards or supports passing through opposite sides of the flask andthrough the guides, and a pattern resting 011 or supported by saidguards, substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand and seal.
